This study investigated if the concentrations measured at child pushchair and adult inhalation heights (0.8 m and 1.68 m) were different from one another at a roadside locations. Concentrations of PM2.5 mass and reflectance and bioaerosols were significantly higher at the lower (0.8 m) compared to the upper (1.68 m)height. There was no significant difference between the lower and upper heights for nitrogen dioxide (NO2 ) concentrations.
